Evolution may be dominated by biotic factors, as in the Red Queen model, or abiotic factors, as in the Court Jester model, or a mixture of both. The two models appear to operate predominantly over different geographic and temporal scales: Competition, predation, and other biotic factors shape ecosystems locally and over short time spans, but extrinsic factors such as climate and oceanographic a...

PURPOSE OF THE STUDY In recent years, there has been an increasing focus on the role of safety culture in preventing costly adverse events, such as medication errors and falls, among nursing home residents. However, little is known regarding critical organizational determinants of a positive safety culture in nursing homes. The aim of this study was to identify organizational climate predictors...

In Ethiopia, climate change and associated risks are expected to have serious consequences for agriculture and food security. This in turn will seriously impact on the welfare of the people, particularly the rural farmers whose main livelihood depends on rain-fed agriculture. The level of impacts will mainly depend on the awareness and the level of adaptation in response to the changing climate...

A national, representative survey of the U.S. public found that Americans have moderate climate change risk perceptions, strongly support a variety of national and international policies to mitigate climate change, and strongly oppose several carbon tax proposals. Drawing on the theoretical distinction between analytic and experiential decision-making, this study found that American risk percep...

Advances in the phenology of organisms are often attributed to climate change, but alternatively, may reflect a publication bias towards advances and may be caused by environmental factors unrelated to climate change. Both factors are investigated using the breeding dates of 25 long-term studied populations of Ficedula flycatchers across Europe. Trends in spring temperature varied markedly betw...

The lack of integrated long-term data on health, diseases, and toxicant effects in Arctic marine mammals severely limits our ability to predict the effects of climate change on marine mammal health. The overall health of an individual animal is the result of complex interactions among immune status, body condition, pathogens and their pathogenicity, toxicant exposure, and the various environmen...

Global warming and climate change affect aquatic stocks´s growth, biological activity and physiological behaviors because aquatic CPUE is influenced by physical and chemical factors such as temperature, salinity, wind speed and its direction and sea current. In this research, the relation between the time series shark CPUE data in the Iranian waters of Persian Gulf and Gulf of Oman with the env...

The purpose of this study was to investigate the role of job factors, constructive organizational climate and extra-organizational factors on the transfer of learning with the mediating role of learning transfer mechanisms on the consequences of learning. The research method was descriptive-survey and based on structural equations. The statistical population of the study included all managers, ...

The climate analog approach is often considered a valuable tool for climate change impact projection and adaptation planning, especially for complex systems that cannot be modeled reliably. Important examples are smallholder farming systems using agroforestry or other mixed-cropping approaches. For the projected climate at a particular site of interest, the analog approach identifies locations ...
